[0002] The building engineering unloading platform is an important facility for temporarily storing and transferring building materials at the construction site, usually located outside the building, and connected with vertical transportation equipment such as construction elevators or tower cranes. It is mainly used to safely transfer materials from the ground or other floors to the construction layer and ensure that workers can conveniently carry and stack these materials. The building engineering unloading platform includes an end beam outside the building, wherein both ends of the end beam are installed with a branch arm beam, and a footboard is installed in the space formed by the branch arm beam and the end beam, so that the end of the branch arm beam away from the end beam extends into the building, and then the branch arm beam is installed on the bottom plate inside the building with a U-shaped screw rod. The length of the branch arm beam is fixed and cannot be adjusted according to the on-site environment of the building, so that the position of the fixed point where the branch arm beam is fixed on the bottom plate of the building cannot be adjusted. In order to adapt to the on-site environment of the bottom plate of the building, branch arm beams of different lengths need to be made, resulting in that the building engineering unloading platform is difficult to be universal.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: a construction engineering unloading platform, including an end beam 1, with support beams 5 installed at both ends of the end beam 1. A footboard 22 is installed in the space formed by the two support beams 5 and the end beam 1. A plurality of horizontal tubes 3 are evenly arranged on the lower surface of the footboard 22. The two ends of the horizontal tubes 3 are respectively connected and fixed to the two support beams 5. Two longitudinal tubes 2 are provided on the lower side of the horizontal tubes 3. The longitudinal tubes 2 are connected and fixed to the plurality of horizontal tubes 3. The longitudinal tubes 2 and the horizontal tubes 3 cooperate with each other to support the footboard 22. A railing 4 is provided on the upper side of the footboard 22. The railing 4 is connected and fixed to the end beam 1 and the support beams 5. The railing 4 has a U-shaped structure. The design of the railing 4 improves safety.

[0022] See Figures 1-4 Each of the two support beams 5 has a positioning beam 21 on the side away from the end beam 1. A first lug 9 is fixedly connected to the end of the support beam 5 near the positioning beam 21, and a second lug 11, which mates with the first lug 9, is fixedly connected to the end of the positioning beam 21 near the support beam 5. Both support beams 5 have studs 6 on their opposite sides, which pass through the first lug 9 and the second lug 11. A first nut 8 is provided on both sides of the first lug 9 along the length of the stud 6, and the first nut 8 is threadedly connected to the stud 6. A second nut 8 is provided on both sides of the second lug 11 along the length of the stud 6. The second nut 10 is threadedly connected to the stud 6. The distance between the positioning beam 21 and the support beam 5 is adjusted according to the site environment of the building's base plate. At this time, the relative position of the stud 6 and the first lug 9 and the second lug 11 changes. When the distance between the positioning beam 21 and the support beam 5 meets the requirements, the first nut 8 and the second nut 10 are used to restrict the relative position of the first lug 9, the second lug 11 and the stud 6 respectively. This allows the position of the fixing point to be adjusted according to the needs of the building on site, without the need to make support beams 5 of different lengths, thus achieving universality.

[0023] See Figure 1 and Figure 3Each of the two positioning beams 21 has a detachable vertical tube 13 installed at the end furthest from the support beam 5. An inner tube 14 is inserted inside the vertical tube 13. Multiple first through holes are arranged vertically on the two parallel sides of the inner tube 14, and multiple second through holes are arranged vertically on the two parallel sides of the vertical tube 13. Fasteners consisting of limit screws and nuts are inserted into the channel formed by the aligned first and second through holes. A detachable inclined tube 19 is installed on the outer surface of the upper end of the vertical tube 13. The end of the inclined tube 19 furthest from the vertical tube 13 is connected to the positioning beam 21 by bolts. A rectangular head 16 is fixedly connected to the upper end of the inner tube 14. A vertical screw hole is opened on the upper surface of the rectangular head 16, and a screw rod 17 is threaded into the vertical screw hole. A top seat 15 is connected to the upper end of the screw rod 17. Multiple fixing holes are evenly distributed on the upper surface of the top seat 15. After the position of beam 21 is restricted, the relative positions of inner tube 14 and vertical tube 13 are adjusted, thereby changing the length of the structure formed by inner tube 14 and vertical tube 13. Then, the relative positions of inner tube 14 and vertical tube 13 are restricted by fasteners formed by limit bolts and nuts, which facilitates the adjustment of the distance between top seat 15 and building top plate. Tightening screw 17 further changes the position of top seat 15, realizing fine adjustment of the relative position of top seat 15 and building top plate, which is conducive to contact between top seat 15 and building top plate. Top seat 15 is installed on building top plate with bolts, improving the stability of the overall structure. A connecting rib 18 is provided between the two vertical tubes 13. The two ends of the connecting rib 18 are connected to the two inner tubes 14 respectively by bolts. The connecting rib 18 and the inclined tube 19 cooperate with each other to improve the stability of the installation of vertical tube 13.

[0024] See Figures 1-3 U-shaped seats 12 are installed on the upper surface of the first ear 9 and the upper surface of the second ear 11. A stiffening plate 7 is provided on the upper side of the stud 6, which is arranged parallel to the stud 6. The stiffening plate 7 passes through the U-shaped seats 12 on the first ear 9 and the second ear 11. A threaded hole is opened on the upper surface of the U-shaped seat 12. A positioning screw 20 for limiting the relative position of the stiffening plate 7 and the U-shaped seat 12 is threaded in the threaded hole. The stiffening plate 7 is inserted into the two U-shaped seats 12 on the same side. Then, the positioning screw 20 is used to limit the relative position of the stiffening plate 7 and the U-shaped seat 12. Thus, under the action of the stiffening plate 7, the force of the building material acting on the pedal 22 is prevented from acting entirely on the stud 6, thereby protecting the stud 6.
